Description
0: Speed control (C5-01 to
C5-07)
1: Torque control
:This function is only available
in flux vector control mode. u vecto co t o ode.
To use the function for switch- h i i h
ing between speed and torque
control, set to 0 and set the
multi-function input to "speed/
torque control change."
Sets the torque reference delay
time in ms units.
:This function can be used to ad-
just the noise of the torque con-
trol signal or the responsive- trol signal or the responsive-
ness with the host controller.
When oscillation occurs during
torque control, increase the set
value.
Sets the speed limit command
method for the torque control
mode.
1: The analog input limit from an 1: The analog input limit from an
analog frequency reference
terminal (terminals 13 and 14.)
2: Limited by d5-04 constant set-
ting values.
Sets the speed limit during torque
control as a percentage of the
maximum output frequency.
:This function is enabled when
d5 03 i d5-03 is set to 2. Directions are t t 2 Di ti
as follows.
+: run command direction
−: run command opposite direc-
tion
Sets the speed limit bias as a per-
centage of the maximum output
frequency.
:Bias is given to the specified i i t th ifi d
:Bi
speed limit. It can be used to
adjust the margin for the speed
limit.
Sets the delay time from inputting
the multi-function input "speed/
torque control change" (from ON
to OFF or OFF to ON) until the
control is actually changed, in ms
units.
:This function is enabled when
the multi-function input "speed/ p p
t torque control change" is set. In t l h " i t I
the speed/torque control
switching timer, the three ana-
log inputs hold the values of
when the "speed/torque control
change" changes. Always be
sure to allow time for this pro-
cess to finish completely.
